Question

In the question number 62, the distance from the thrower to the point where the ball returns to the same level is
A. 58 m
B. 68 m
C. 78 m
D. 88 m

Answer 1

Correct Answer - C
The dsitance from the thrower to the point where the ball returns the same leve is
`R=(u^(2)sin2theta)/(g)=((30ms^(-1))^(2)(sin60^(@)))/(10ms^(-2))~~78`
